<div class="textblock"><p>Implements a Limited-Memory-CMA. </p>
<p>This is the algorithm as proposed in Ilya Loshchilov, "A Computationally Efficient Limited Memory CMA-ES for Large Scale Optimization" with a few corrections regarding the covariance matrix update.</p>
<p>The algorithm stores a subset of previous evolution path vectors and approximates the covariance matrix based on this. This algorithm only requires O(nm) memory, where n is the dimensionality and n the problem dimensionality. To be more exact, 2*m vectors of size n are stored to calculate the matrix-vector product with the choelsky factor of the covariance matrix in O(mn).</p>
<p>The algorithm uses the population based step size adaptation strategy as proposed in the same paper. </p>
